Carya illinoensis nutrition bag seedling cultivation method

The invention provides a carya illinoensis nutrition bag seedling cultivation method. The method includes: mixing perlite, wood flour, slow release fertilizer and field mud according to a mass ratio of (4-5):(9-11):1:(2-4) to obtain a matrix, removing water to keep the relative humidity of 45-55 after the matrix is subjected to sterilization and deinsectization in water, soaking carya illinoensis seeds in gibberellin with the concentration of 400ppm for 5-8 days, storing the soaked seeds in sand for 6-8 days, then sowing the seeds stored in sand into a nutrition bag and covering the nutrition bag with arched film, removing the arched film when the rate of emergence reaches 45%-50%, watering, weeding, spraying insecticide and fertilizing after the arched film is removed, and grafting after the ground diameter of nursery stocks reaches more than 0.4cm. Cultivated carya illinoensis nutrition bag seedlings are complete in roots, survival rate of afforestation is high, land for seedling cultivation can be effectively saved, and seedling cultivation period is shortened, so that seedling cultivation cost is reduced, annual seedling cultivation can be realized, and seedling cultivation scale is larger.
